Hi all!
This is my first post! I'm a student in Electrical engineering, but i'm not quite through my second year yet so i've not had the major circuits course.
I don't think I can wait any more on this project, for I am a forgetful man... lol
I have a Nissan Xterra (2000) and it doesn't have that neat feature of auto shutoff lights that a lot of vehicles have nowadays. So, I plan to add that feature See, I have come back to a dead battery many times because I leave the lights on.
I have this all planned... i'm going to move the main power of the headlamps to come from the ignition switch instead of directly from the battery and put the circuit in between the ignition and the factory headlamp switch. That way, I still have a little control over the lights.
Do any of you have any suggestions on how i could improve the circuit? And is that 12V relay just one of those that I can buy at an auto parts store i.e. an 85, 87, etc. relay?
The circuit is attached! (actually, It probably needs to look more like LightsCircuits2 doesn't it, or are 1 & 2 the same?)
This circuit is supposed to delay the power-on for 7 seconds (lessen battery load while starting the engine) and delay-off to allow me to see where i'm walking at night for 15 seconds. I have all of the resistor/capacitor values set.
